STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 445,182, dated January27', 1891.

Application filed July 13, 1885l To @ZZ whom 'it may concern:

Be it known that I, JOHN JOHNSON, a citizen of the United States,residing at Baton Rouge, parish of East Baton Rouge, and State ofLouisiana, have invented certain new and useful Improvements inPendant-Sets for Stem-Winding Vatches, of which the following is aspecification.

This invention relates to improvements in hand setting devices for stemwinding watches in which the hand-setting devices are normallydisengaged from the stem-winding mechanism, but which may be connectedtherewith for the purpose of utilizing said stem-windin g mechanism forsetting the hands of the watch and without operatin g the watchactuatingmechanism. y

The objects of this invention are to provide means for detaching thestem or key-pipe from the movement, whereby the said movement may beremoved from the case; to provide for detaching the stem from themovement by means of the actuating-lever for -the handsetting device, tohave a flexible lever-connection between the yoke an d key-pipe, wherebythe actuating-lever by means of its flexibility may be withdrawn fromconnection with said key-pipe without disturbing its fulcrum orconnection with the yoke; to provide means for connecting anddisconnecting the springlever from 'the key-pipe without interferingwith the operation of the lever as a lever, whether connected ordisconnected, and to provide certain details of construction hereinaftermore fully described, and illustrated in the accompanying drawings.

Figure l represents an enlarged face view of a watch-movement, showingmy invention applied thereto; Fig. 2, an enlarged section on line Fig.l; Fig. S3, a detail section on line y y, Fig. 1; Fig. fl, a detailperspective of spring-lever for connecting the key-pipe and hand-settingmechanism; Fig. 5,a detail view of the key-pipe; FiO. 6,an enlarged faceview of awatch-movement, showing a modification of my invention; Fig. 7,a section on line a a, Fig. 6, and Fig. 8 a detail section on line l)l), Fig. 6; Fig. D, a detail perspective of the connecting-lever; Fig.10, a detail view of the key-pipe; Fig. ll, a detail perspective of amodification of the connecting-lever.

Serial No. 171,425. (No model.)

Similar letters of reference indicate the same parts in the severalgures of the drawings.

A indicates a bell-crank spring-lever pivoted at a suitable point uponthe movementplate B, and having upon one of its arms O a projection orguide D, adapted to engage a groove D', formed upon an elevating-screwE, for the purpose hereinafter described.

Depending or bent down from the arm O, Figs. 2 and 4, just to the rearof the guide, is the projection F, adapted to engage the groove G,formed upon the key-pipe. It is obvious that two small pins or anyequivalent device might be employed instead of the projection on the armO. The projection F, working in the said groove G, not only permits thefree rotation of the key-pipe, but also serves to form a connectionbetween the bell-crank lever and the key-pipe, whereby the engagingrocating the key-pipe. The stem orkey-pipe illustrated (see Fig. 2) inconnection with this movement is designed to be used with a femalewinding-pinion, and the employment of my device in connection with amale winding-pinion is illustrated in Figs. G, 7, and S, and will bedescribed hereinafter. The other arm II of the bell-crank lever isadapted to engage a projection I, formed on the yoke Il', so that whenthe actuating-arm O is drawn out by means of the stem the arm II willcause the projection I to be depressed, and thus throw thespring-winding mechanism out of gear and at the same time throw thehand-setting device into gear, when any rotation of the stem will causethe hand-setting device to operate and set the hands at any desiredpoint. Bearing respectively against the yoke and the lever arespring-arms J J projecting from a base J 2 and ser ring to press saidyoke and lever away from each other when the key-pipe is in its normalposition-that is, not drawn outwardly, as shown in dotted lines in Fig.l.

As a means for detaching lever A entirely from the key-pipe, forremoving the movement, and for maintaining the said lever in itsoperative position when a movement is set in the case, I have provided ascrew E, which works in the movement-plate B and projects through thebottom plate B". The end of the end of said lever may be actuated byrecip- IOO screw projecting above the top plate is provided with anordinary screw-head, while its other end without the usual head isgrooved, as shown at E', for the reception of a screwdriver, for inpractice it is more convenient to actuate the screw from this end,because the upper end will be covered by the dial. Below the head properis a shoulder E2, which may serve to limit the movement of the screw,but is mainly for the purpose of forming a connection with thehead-groove D for embracing the end D ofthe lever-arm C, projectingtherein, so lthat when the 4screw is moved in either direction it willcorrespondingly actuate the lever. The said arm C of thislever ispreferably a spring-arm, and when the screw E is elevated it carrieswith it the spring-arm C, lifting the depending projection F on said armfree from the groove on the stem or key-pipe, thereby permitting theready removal of the key-pipe from the case.

The upper end of the elevating screw-head, as shown, may be providedwith a star-shaped head similar to that shown in Fig. 6, and thus renderthe said screw capable of operation by hand or-otherwise from the faceof t-he movement when employed in connection with the movement of anopen-faced watch.

The projection or guide D is made of sut'- ficient length to permit thefull movement of the arm C without becoming disengaged from the groove Dformed inthe head of the screw E, as before described.

Fig. l of thc drawings represents the springwinding mechanism in gear,and if now it is desired to set the hands the operation is as follows:The key-pipe is drawn out by means of the crown, and carries with it theactuatin g-arm of the lever, connected thereto by the dependingprojection formed near the end of said arm, engaging the groove in theend of the key-pipe. The outward movement of the actuating-arm of' thelever causes the other arm to come in contact with and depress the.projection on the yoke, thereby causing the yoke to assume the positionshown by dotted lines in Fig. l, throwing the spring-winding mechanismout of gear and the hand-setting device into gear ready for operation bythe stem.

Figs. 6, 7, and 8 represent a modification of my device when employed inconnection with a movement having a male winding-pinion. In Fig. l thelever employed is of the first class, while in this case the lever a isof the third class, and has a pin b on its free end engaging a suitablenotch formed in a projection on the yoke c, as clearly illustrated inFig. 6. This project-ion also has a second notch b,in which seats thepin b when the lever is at the extreme of its forward movement to form alock for the lever when in that position and obviating the necessity ofa retaining-spring. 'lhe depending projection d engages a suitablegroove c, formed between two flanges on the end of thekey-pipe f. Theelevating-screw is located between the keypipe and fulcrum of the lever,and in cases where the back and center of the watch-case are formed inone piece it is preferred to use the star-shaped head g on theelevating-screw flush with or projecting slightly beyond the dial, to beoperated by hand or otherwise, in order that the elevation of the saidscrew, permitting the removal of the stem or keypipe, may be effectedfrom the upper side or face of the movement. v

It is obvious that the elevating-screw could not be operated from theback of the movement, as in the first case, and this deviceis designedto overcome that objection.

The pin 7L, which forms the fulcrum for the lever, is of sufficientlength to permit the elevation of the said lever until the projection dclears the'groove on the stem or key-pipe without the said leverbecoming disengaged therefrom.

I do not limit myself to the employment of ythe groove upon the key-pipein which to engage the projection on the lever, for it is obvious thatvarious forms of connection between the said members may be made withoutdeparting from the spirit of my invention, such, for instance, as shownin Fig. Il, by forming a single flange upon the key-pipe and providing asuitable notch upon a proj ection formed on the under side of the lever;or two pins` might be employed instead of this notch and effect the sameresults.

It will be observed that the depending projection on the lever inconnection with the groove on thekey-pipe constitutea separableconnection between the lever and key-pipe, whereby the said key-pipe maybe detached from the movement.

In conclusion, it maybe observed that either form of the hand-settingdevices illustrated in the drawings may easily be adapted for use inconnection with either a male or female winding-pinion without adeparture from this invention, although I have illustrated them eachrespectively in connection with the winding-pinion they-are-preferablyemployed with.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-
